Since you're talking about interrupts, by int(), I assume you actually mean fnInt()?

fnInt(1,2) would try to activate Lbl 1 as an interrupt, and I'm guessing you don't have a subroutine called "1" in your program, so getting the label missing error would make sense.

I can't be sure, but Axe seems to be pretty stable for now, so I would guess the RAM clears are being caused by your code itself, not a bug. You would need to post it so somebody could look at it and determine if it's a problem with your source code or if it is in fact a bug.

Actually, you may be onto something. I assumed 0.4.3 fixed the label errors, but apparently it didn't. The problem appears to be with the fnInt() command. As far as I can see, the problem is that, using whatever shortened character set Quigibo uses to store label name data (if I had to guess, 0-9 A-Z), the first character of the label name called is always misinterpreted. It seems that this character is stored with a value 10 less than what it should be. In one of my programs, I want to enable "INT" as an interrupt. When compiling, fnInt(INT,6) throws a missing label error, claiming that "8NT" is missing. fnInt(ZNT,6) throws an error, claiming that "PNT" is missing. In both of these names returned, the first character has a value 10 less than what it should be. fnInt(SNT,6), however, compiles correctly, as S is 10 letters ahead of I in the alphabet.

This error only appears to happen with fnInt(), not sub() or Goto.

Do you mean the first time you compile the error show up and the second attempt it won't? Do you need to do something inbetween (such as Garbage Collecting, archiving/unarchiving)?
